Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668590, here are decompositions:

13 + 8668577 = 8668590
19 + 8668571 = 8668590
37 + 8668553 = 8668590
41 + 8668549 = 8668590
43 + 8668547 = 8668590
67 + 8668523 = 8668590
71 + 8668519 = 8668590
89 + 8668501 = 8668590

Showing the first eight; more decompositions exist.
